uBITX Microphone Preamplifier

uBITX Microphone Preamplifier: If you own a uBITX transceiver—whether it’s the V3, V4, or V6—you’ve likely experienced the infamous low microphone audio issue. This isn’t a defect in your particular radio; it’s a well-known characteristic across all uBITX versions. The microphone input stage simply doesn’t provide enough gain for electret microphone elements, forcing operators to speak unnaturally loud or practically yell to achieve full power output.
